On Saturday afternoon, thousands of pillow-bearing Cantabrigians gathered on Cambridge Common and waited patiently for the signal. Then, at exactly 3:00 p.m., the crowd erupted into feathery chaos.

Brought together through Facebook and Twitter by a Boston-based group who call themselves the Banditos Mysteriosos, strangers gleefully whacked each other in an annual celebration of International Pillow Fight Day. Some wore ridiculous costumes, and others even formed teams. The fight lasted nearly an hour, attracting a large audience of park-dwelling residents and pedestrians.
